During the test, you can switch the uniformity detection and
the atomization detection by the [Oil drain] button. The
system default solenoid valve is closed. At this time, the
uniformity detection can be performed. If the [Oil drain] button
is pressed, the solenoid valve drains. At this time, the
atomization test can be performed.
The default “cylinder number” parameter of the system is 0,
that is, all the injectors are working during operation. You can
select a certain injector to work by setting the “cylinder
number” parameter.
At the time of detection, the system pressure can be adjusted
by the [Supercharge] and [Decompression] buttons.

parameters, then press the ►or◄ key, this can achieve
variable working condition simulation.
The injection angle of the injector should be consistent, the
atomization should be uniform, and there is no jet
phenomenon, otherwise it needs to be replaced.
The detection of the electrical characteristic parameter of the
minimum injection opening pulse width of the injector can be
performed under the atomization detection to compare the
difference of this parameter among all the injectors of the
same engine. That is, after setting a certain cylinder or all
cylinders, starting from the minimum injection pulse width
during operation, gradually increase the pulse width until the
injector can be observed to open the fuel injection (observable
by the backlight), and the spray is set at this time. The oil
pulse width is the minimum injection opening pulse width of
the injector. Thereby observing the difference in the minimum
opening pulse width of the injector.
